Application led (lctober 18, 1927. Serial No. 226,985.

This invention relates to certain new and useful improvements in Windshieldheater and more particularly to a heaterdevice removably attached to the windshield Iof a motor vehicle for the purpose of preventing the accumulation of moisture, snow or ice upon the glass Windshield and to insure clear vision through the windshield at.all

. times.

A further object of the invention is to provide a heater attachment for the windi shields of motor vehicles wherein the heater device is carried by a spring member that is removably and slidably associated with the windshield frame to permit the heater to be shifted transversely of the windshield in the desired direction for the proper distribution f l of heated air onto the windshield glass.

With the above and other objects in view that will appear as the nature of'the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown'in the accompanying drawing and claimed.

In the accompanying drawing, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 fragmentarily illustrates the'section, the windshield Vof a motor vehicle, a part of the top and body, together with the I vehicle motor. and showing the heater atlio tachment lin position on thewindshield frame andi in communication with an air heatingl chamber associated with' the exhaust manifold of the motor;

Figure 2l is a fragmentary rear elevational view of the windshield frame with the heater in position;y

Figure 3 is an enlarged front. elevational View of theheater device; and y Figure 4 is a eross-sectionalview taken on -line'4-4 of Figure 3 showing the air chamber of the heat-ing device and the c shion blocks for spacing the heater from the'windshield glass. V

In Figure 1 there isillustrated the front end o f .the top. of the motor vehicle desiglnated'by the reference numeral 1 and the cowl 2 `with theA windshield disposed between the top and cowl and comprising nthe usual tubular frame 3 that is grooved to receive'the edges of and confine the Windshield glass 4. The reference numeral 5 designates the vehicle motor with the exhaust pipe 6 directed rearwardly thereof.

The heater device is removably and slidably associated with the windshield frame 3 and the heated air flowing therefrom -onto the windshield glass 4 is supplied by a flexible conduit that is in communication with a heating chamber associated with the exhaust pipe of the motor. The windshield dheater comprises a casing or chamber of elongated formation having a rear eurvedwall f? that is closed at its upper end and open at its lower end -with outwardly directed edge flanges 8 as shown in Figures 2 and 4. faceplate 9 is placed in flat engagement with the-'edge flanges 8 and is permanently' secured thereto in any manner, such as by soldering or the like. The face plate 9 is provided with a plurality of openings 10 as shown in Figure 3 for directing heated air onto thewindshield glass 4.

The lower end of the rear curved wall 7 ofthe heater device is rolled into circular formation as at 11 for the attachment of one endof the flexible conduit 12. A tubular air heating chamber 13 is associated with the exhaust pipe 6 and has a funnel-shaped inlet 14 at its forward edge, the rear end of the tubular heating chamber 13 having the adjacent end of the flexible conduit 12V connected therewith. Air entering the `tubular heating chamber 13 through the funnel- 'shaped opening 14 is heated by the exhaust pipe 6 and is delivered 'to the flexible conduit 12 to the heating device above described. A The heatipg device isv carried by a member that is removably andadjustably mounted on the windshield frame 3 to permit the heating device to be moved over the windshield glass to the desired point. The supporting means for the heating device comprises a spirng member 15 having the heating device attached thereto as at 16 intermediate its ends while the opposite ends of the spring member aretapered and received bethat heated air may'pass through Lthe opening 10 and onto said glass, the face plate 9 of the heater device carries cushion blocks 17 projecting outwardly fromthe face of said plate and attached thereto by screw studs 18.

The cushion blocks 17v hold the heating device spacedvfrom the windshield glass soy that air may flow through the openings and onto the glass 4 for heating the same.

y T he heater device may be shifted trans, 5 versely of the Windshield frame with t-he spring member retaining the same in position on the Windshield frame and also in its shifted position. vhen the heater isout of use, the same may be shifted to one side l" of the Windshield, or disengaged therefrom.

As shown in Figures 1 and 2, the lower end of the spring member 15 that carries the heater device is formed with a loop ortion 19 through which the flexible con uit 12 L" extends, the flexible conduit. after passing through the loop 19 being positioned between the spring member l5 and the Windshield glass 4. The spring member and heater device may remain engaged with .the

2" Windshield frame and the flexible conduit '-5 operation is accomplished by the valve de vice 20 mounted in the flexible conduit l2 the operating device for the choke valve. v From the above detailed description of the invention, it is believed that the construc- 7 tion and operation thereof vvill at once be apparent, and While there is herein shovvn and described the preferred embodiment of the invention it is nevertheless to be understood that minor changes may be made therein Without departing from the spirit and scope of the invention as claimed.

lVhat I claim as new is y I n a Windshield heater for motor vehicles, the combination with the Windshield frame, of a s ring member detachably engaged at its en s with the frame, a heater device carried by the spring member, the heater device comprising a" casing having openings in one wall directed toward the windshield glass, a flexible conduit attached to the heater, and an air heating chamber associated with the motor exhaust pipe and having the` flexible conduit attached thereto.

In testimony whereof I afix my signature.
